2015-09-27MIPS: Initialise MAARs on secondary CPUsPaul Burton
MAARs should be initialised on each CPU (or rather, core) in the system in order to achieve consistent behaviour & performance. Previously they have only been initialised on the boot CPU which leads to performance problems if tasks are later scheduled on a secondary CPU, particularly if those tasks make use of unaligned vector accesses where some CPUs don't handle any cases in hardware for non-speculative memory regions. Fix this by recording the MAAR configuration from the boot CPU and applying it to secondary CPUs as part of their bringup.

2015-09-27MIPS: mm: compile maar_init unconditionallyPaul Burton
maar_init was previously only compiled when CONFIG_NEED_MULTIPLE_NODES was not set, which has been fine since it is only called from the standard implementation of mem_init which has the same condition. In preparation for calling it from the SMP startup code on secondary CPUs, move maar_init outside of the #ifndef such that it is always compiled.

2015-09-27irqchip: mips-gic: Fix pending & mask reads for MIPS64 with 32b GIC.Paul Burton
gic_handle_shared_int reads the GIC interrupt pending & mask registers directly into a bitmap, which is defined as an array of unsigned longs. The GIC pending registers may be 32 bits wide if the CM is older than CM3, regardless of the bit width of the CPU, but for MIPS64 kernels the unsigned longs in the bitmap will be 64 bits wide. In this case we need to perform 2 x 32 bit reads per 64 bit unsigned long in order to avoid missing interrupts.

2015-09-27MIPS: CM: Provide a function to map from CPU to VP ID.Paul Burton
The VP ID of a given CPU may not match up with the CPU number used by Linux. For example, if the width of the VP part of the VP ID is wider than log2(number of VPs per core) and the system has multiple cores then this will be the case. Alternatively, if a pre-r6 system implements the MT ASE with multiple VPEs per core and Linux is built without support for the MT ASE then the numbers won't match up either.

2015-09-26Merge branch 'vxlan-ipv4-ipv6'David S. Miller
Jiri Benc says: ==================== vxlan: support both IPv4 and IPv6 sockets Note: this needs net merged into net-next in order to apply. It's currently not easy enough to work with metadata based vxlan tunnels. In particular, it's necessary to create separate network interfaces for IPv4 and IPv6 tunneling. Assigning an IPv6 address to an IPv4 interface is allowed yet won't do what's expected. With route based tunneling, one has to pay attention to use the vxlan interface opened with the correct family. Other users of this (openvswitch) would need to always create two vxlan interfaces. Furthermore, there's no sane API for creating an IPv6 vxlan metadata based interface. This patchset simplifies this by opening both IPv4 and IPv6 socket if the vxlan interface has the metadata flag (IFLA_VXLAN_COLLECT_METADATA) set. Assignment of addresses etc. works as expected after this. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2015-09-268139cp: Fix GSO MSS handlingDavid Woodhouse
When fixing the TSO support I noticed we just mask ->gso_size with the MSSMask value and don't care about the consequences. Provide a .ndo_features_check() method which drops the NETIF_F_TSO feature for any skb which would exceed the maximum, and thus forces it to be segmented by software. Then we can stop the masking in cp_start_xmit(), and just WARN if the maximum is exceeded, which should now never happen. Finally, Francois Romieu noticed that we didn't even have the right value for MSSMask anyway; it should be 0x7ff (11 bits) not 0xfff.

2015-09-26tools/power turbostat: SKL: Adjust for TSC difference from base frequencyLen Brown
On a Skylake with 1500MHz base frequency, the TSC runs at 1512MHz. This is because the TSC is no longer in the n*100 MHz BCLK domain, but is now in the m*24MHz crystal clock domain. (24 MHz * 63 = 1512 MHz) This adds error to several calculations in turbostat, unless the TSC sample sizes are adjusted for this difference. Note that calculations in the time domain are immune from this issue, as the timing sub-system has already calibrated the TSC against a known wall clock. AVG_MHz = APERF_delta/measurement_interval need no adjustment. APERF_delta is in the BCLK domain, and measurement_interval is in the time domain. TSC_MHz = TSC_delta/measurement_interval needs no adjustment -- as we really do want to report the actual measured TSC delta here, and measurement_interval is in the accurate time domain. %Busy = MPERF_delta/TSC_delta needs adjustment to use TSC_BCLK_DOMAIN_delta. TSC_BCLK_DOMAIN_delta = TSC_delta * base_hz / tsc_hz Bzy_MHz = TSC_delta/APERF_delta/MPERF_delta/measurement_interval need adjustment as above. No other metrics in turbostat need to be adjusted. Before: CPU Avg_MHz %Busy Bzy_MHz TSC_MHz - 550 24.84 2216 1512 0 2191 98.73 2219 1514 2 0 0.01 2130 1512 1 9 0.43 2016 1512 3 2 0.08 2016 1512 After: CPU Avg_MHz %Busy Bzy_MHz TSC_MHz - 550 25.05 2198 1512 0 2190 99.62 2199 1512 2 0 0.01 2152 1512 1 9 0.46 2000 1512 3 2 0.10 2000 1512 Note that in this example, the "Before" Bzy_MHz was reported as exceeding the 2200 max turbo rate. Also, even a pinned spin loop would not be reported as over 99% busy. Signed-off-by: Len Brown <len.brown@intel.com>
2015-09-26tools/power turbostat: KNL workaround for %Busy and Avg_MHzHubert Chrzaniuk
KNL increments APERF and MPERF every 1024 clocks. This is compliant with the architecture specification, which requires that only the ratio of APERF/MPERF need be valid. However, turbostat takes advantage of the fact that these two MSRs increment every un-halted clock at the actual and base frequency: AVG_MHz = APERF_delta/measurement_interval %Busy = MPERF_delta/TSC_delta This quirk is needed for these calculations to also work on KNL, which would otherwise show a value 1024x smaller than expected.

2015-09-25IB/ipoib: increase the max mcast backlog queueDoug Ledford
When performing sendonly joins, we queue the packets that trigger the join until the join completes. This may take on the order of hundreds of milliseconds. It is easy to have many more than three packets come in during that time. Expand the maximum queue depth in order to try and prevent dropped packets during the time it takes to join the multicast group. Signed-off-by: Doug Ledford <dledford@redhat.com>

2015-09-26ACPI, PCI, irq: Do not share PCI IRQ with ISA IRQJiang Liu
Avoid IRQs occupied by ISA IRQs when allocating IRQs for PCI link devices, otherwise it may cause interrupt storm due to incompatible pin attributes. This issue was triggered on a KVM virtual machine, which 1) uses IRQ9 for SCI in high level mode. 2) defines an PCI interrupt link device (LNKS) with IRQ9 as the only possible irq. 3) has an PCI device referring to link device LNKS. So it causes interrupt storm when enabling the PCI device because PCI IRQ works in low level mode.

2015-09-26ACPI / EC: Fix a memory leak issue in acpi_ec_query()Lv Zheng
When query handler is not found, "result" is actually stil 0, and "struct acpi_ec_query" is not NULL, so the deletion code of "struct acpi_ec_query" at the end of the function cannot be invoked. As a consequence, memory leak can be observed.

2015-09-25Merge branch 'listener-sock-const'David S. Miller
Eric Dumazet says: ==================== dccp/tcp: constify listener sock Another patch bomb to prepare lockless TCP/DCCP LISTEN handling. SYNACK retransmits are built and sent without listener socket being locked. Soon, initial SYNACK packets will have same property. This series makes sure we did not something wrong with this model, by adding a const qualifier in all the paths taken from synack building and transmit, for IPv4/IPv6 and TCP/dccp. The only potential problem was the rewrite of ecn bits for connections with DCTCP as congestion module, but this was a very minor one. ==================== Signed-off-by: David S.
